The New York Times will have an article in their Sunday paper titled “For Democrats, Increased Fears of a Long Fight” in which it appears that many superdelegates are beginning to realize that it is Obama or bust.

“If we get to the end and Senator Obama has won more states, has more delegates and more popular vote,” said Representative Jason Altmire, Democrat of Pennsylvania, who is undecided, “I would need some sort of rationale for why at that point any superdelegate would go the other way, seeing that the people have spoken.”

“It would be nice to find a way to wrap it up,” said Representative Chris Van Hollen of Maryland, chairman of the Democratic Congressional Campaign Committee, who has not committed to either candidate. “If the current trajectory of the debate continues, the divisions will make it more difficult for many of our candidates.”

In Ohio, Senator Sherrod Brown would seemingly have an easy task. Mrs. Clinton won his state by 10 points. If the nominating fight had to be resolved by party leaders, wouldn’t he side with her? Not necessarily.

“It’s the overall popular vote, it’s the overall delegates, it’s who is bringing energy to the campaign, it’s who has momentum,” Mr. Brown said. “It should be wrapped up before the convention, and I think it will be.”

“If the votes of the superdelegates overturn what’s happened in the elections, it would be harmful to the Democratic Party,” Ms. Pelosi, Democrat of California, said in an interview to be broadcast Sunday on ABC’s “This Week.”

“Barack’s impressive showing in our state is attractive to me,” said Senator Amy Klobuchar, Democrat of Minnesota, where Mr. Obama beat Mrs. Clinton two to one in the popular vote last month. “If somehow 200 superdelegates decide this, it will be problematic.”
